Personal-lubricating material and method for lubricant manufacture

ABSTRACT

The invention relates to a novel composition and method of manufacturing personal lubricant, commonly known as lube, to combine the most desirable features of disparate existing lube compositions to create a long lasting, oil-based, water soluble, non-toxic, anti-microbial, anti-yeast, non-staining, personal lubricant that can be organically sourced and will not damage commonly used prophylactics.

BACKGROUND OF THE INVENTION

This invention addresses the personal or lubricant industry and more particularly the composition and manufacture of personal or patient lubricant colloquially known as “lube”. Personal lubricant is useful for lubrication during intimate contact or when lubrication is required for the insertion of catheters, colostomy bags and similar medical devices or during ultrasound or similar procedure needing improved skin conduction and surface lubrication to prevent chafing.

Water soluble lubes are generally easy to clean and non-staining but react to friction by de-stabilizing and/or being absorbed by the skin and/or being dissolved by natural lubrication created by mucous membranes or other bodily fluids. This happens at a sufficient rate that re-application is often required during some activities such as coitus. Such an interruption is generally regarded as undesirable.

Further, catheter users who use lube to ease insertion of catheter devices can suffer significant discomfort during the removal of said devices since the lube that eased insertion has largely been absorbed or dissolved by the time of said removal.

Some lubricants currently used in the manufacture of lube (such as silicone) are not water soluble and therefore last much longer as a lubricant on skin as they are not readily dissolved by bodily fluids which are mostly water based. However, these product are not as desirable as water based lubes for both cleaning and biodegradability and their effect on certain polymers used in medical devices or common prophylactics.

Other ingredients commonly used in both types of lube include parabens which though anti-microbial are proving not to be benign when metabolized. In both cases it is possible that silicones and parabens may gradually penetrate skin potentially causing damage to cells. Further, silicone, propylene glycol and numerous other synthetic ingredients can cause an allergic reaction in a significant percentage of the population. It is also common practice to manufacture lube as a transparent product which though desirable in certain applications, make it difficult to see and therefore apply evenly to objects or skin.

Therefore it would be desirable to have a lube that eliminates the need for use of most synthetic ingredients and combines the most desirable characteristics of water soluble and oil based lubes in a formulation that inherently hinders the growth of microorganisms and is easy to apply evenly.

BRIEF SUMMARY OF THE INVENTION

The invention relates to a novel composition and method of manufacture whereby said composition may then be applied to one or more body parts of one or more individuals in order to ease the insertion of devices or body parts into a bodily cavity or orifice acting as a lubricant, typically during some form of intimate activity or during the process of intubation or catheterization. The invention is largely composed of natural ingredients blended in a unique ratio using a unique method that blends oils in a manner that allows them to combine several desirable features yet also be dissolvable with water. This invention is created as a stable, non-toxic, antimicrobial, organic suspension, which can be used as a substitute for current lubricants, yet provides health advantages through the use of organic and naturally derived ingredients that are friendlier to the human metabolism.

DETAILED DESCRIPTION OF THE INVENTION

This invention bridges the gap between two separate types of lube commonly in use; those that are oil based and those that are water based. Traditionally, oil based lubes were derived from natural or synthetic (eg. Silicone) sources and where known to be long lasting. Water based lubes were easier to clean up and are often non-staining. The invention combines several ingredients that have desirable properties which when combined create a lube with numerous combined advantages over those currently available such as antifungal, antibacterial, antiviral, anti-oxidant and analgesic properties.

The invention eliminates the need to use known carcinogens in common lubes that use few certified organic ingredients. The invention uses organic ingredients but does not use microbe affable organic ingredients such as agar or butter. The invention does not use polymers that are acknowledged as damaging to common prophylactics such as latex Condoms.

The invention is non-transparent and thus designed to be easy to apply evenly. The invention is both water soluble and non-staining allowing for easy cleanup. The invention is also environmentally friendly as it is thoroughly biodegradable after disposal.

The invention offers performance enhancements over traditional personal—lubricants due to the differing absorption rates of it ingredients. With some ingredients absorbing faster, others float above those absorbed layers to provide a more lasting effect. Also the aforementioned varying rates offer multi-stage lubrication which creates a gentle increase in pleasurable friction which is desirable during sexual activity. The invention is long lasting and reduces or eliminates the need for reapplication common to existing water soluble personal lubricants.

One embodiment of this invention is formulated using an oil and a wax ester, a poly-saccharide, a natural sweetener that isn't a nutritive source for yeast or bacteria, water and a stabilizing agent, which are then mixed together in varying proportions using specialized rates and temperature controls to achieve optimal viscosity, desired density and solubility. The contents are then introduced to filling machine where they are mixed and then put into sealed containers.

Another embodiment of the formulation is a two part lubricant. The first being more readily absorbed by the skin, sinks into the surface layers forming a seal that prevents the other oil from being absorbed. The other oil, though not incompatible, is resistant to being dissolved by natural lubrication and forms a stable lubricious layer between the sealed layers of skin that rub against each other. This results in a lubricating layer that lasts significantly longer than traditional single stage personal lubricants.

Another embodiment of the formulation is offered as long lasting lube for the benefit of catheter users to allow for easier withdrawal unlike water based lubricants which though functional during insertion, provide no lubrication during withdrawal of the catheter; a process that can be quite painful.

Another embodiment of the formulation is to have the consistency of a lotion and be non-transparent to be easily seen so as to aid in the even application of the lube.

The present embodiments, described in the foregoing, satisfies the need within the art by providing a safe lube that is friendly to the body and discourages the growth of bacteria, yeast and fungus, is condom safe, performs better and is easier to thoroughly clean than that which is currently available.

The lube formulation of the invention offers a variety of benefits not currently satisfied in the marketplace, and provides a new method for greatly reducing the risk of STD posed by commonly used lubes which are not considered safe for use with condoms. Also, being intrinsically antimicrobial, it lessons the possibility of yeast infection and is very friendly to the mucosa of the vagina and urethra.

The lube formulation also reduces the potential for staining and therefore damaging clothing/bedding by having easy water cleanup. The lube formulation is also environmentally “friendly” as it is entirely organic and biodegradable.

The method of the invention describes a means for creating a lube that performs well as a lubricant, is long lasting yet varies the level of lubricity in order to enhance enjoyment of the activity.

The invention is illustrated by the following example:
